Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?
The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
What is synapse?It is the functional relationship of contact between the endings of nerve cells.
This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).
When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.
Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

If Sara has a mass of 60 kg and lives on the fifth floor of her
apartment 18 m above the ground, then what is her
gravitational potential energy?
Use g=9.81 m/s2 for the acceleration due to gravity.
The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
Mass of Sara; [tex]m; = 60kg[/tex]Distance from ground; [tex]h = 18m[/tex]Acceleration due to gravity; [tex]g = 9.81m/s^2[/tex]Gravitational potential energy; [tex]U = \ ?[/tex]Gravitational Potential EnergyGravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;
[tex]U = mgh[/tex]
Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.
[tex]U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J[/tex]
Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

how did the appearance of mendels F generation differ from the appearance of the P generation?
Based on the results, of Mendel's experiments, the F generation had the same appearance as the P generation.
What was Mendel's experiments?In his experiment, Mendel crossed true breeding peas that had white-colored flowers with those that had purple-colored flowers to produce offspring.
The parent's generation were the P generation while the offspring were the F generation.
The results of Mendel's experiments showed that the F1 generation all had purple-colored flowers .
This Mendel concluded was because purple-colored flower trait was dominant over white-colored flower trait.
Therefore, based on his results, the F generation has the same appearance as the P generation.

In which form is energy stored at the end of photosynthesis?
A. Solar energy
B. Electron energy
C. Proton energy
D. Chemical energy
Answer:
D. Chemical Energy
Explanation:
Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.
Most of the energy we get from the sun comes to us as
ultraviolet waves.
visible light.
Xrays.

Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell.
True or false?
Answer:
Explanation:
False sorry if it is wrong
Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
What is Mitosis?A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.
Mitosis follows the same pattern. Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.
Therefore, Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.

Wes met a young woman in one of his classes and was assigned to be in a group with her. Initially, Wes was not particularly interested in her as far as dating was concerned. However, once he found out that she was physically attracted to him, he suddenly felt very attracted to her as well. Wes's increased attraction toward this young woman is BEST explained by the influence of:
proximity.
common group identity.
similarity.
reciprocal liking.
The BEST explanation for Wes's increased attraction toward this young woman is due to the influence of reciprocal liking.
What is reciprocal liking?Reciprocal liking is the attraction or feelings of attraction to someone that a person develops only when he/she learns or becomes aware that the person is attracted to them as well..
Reciprocal liking is also known as reciprocity of attraction.
From the scenario, Wes did not initially like the young woman.
